Product Description

Customized Color VSD Screw Compressor With Super High Efficient Motor



Shanghai rotorcomp Variable speed drive Screw Air Compressor adapting the amount of free air delivered to compressed air demand is the most economical operating method where demand for compressed air fluctuates considerably or where the stored volume is very small or where operating below peak load.

1. High efficiency motor:Using the latest standard motor with new national energy efficiency motors ,using imported SKF bearings.


1. Large starting torque

2. Insulation class F,protection class IP55

3. SKF bearing,low noise,long service life

4. With the installation of gas,non-stop refueling


2. Efficient intake valve:The high quality air inlet valves can reduce energy consumption.


1. Large diameter and low pressure drop.

2.Improve system stability.

3.Ensure effective adjustment control during start-up,operation and stop traffic.


3. Inverter: Frequency changer can control the displacement by adjusting the motor’s speed based

on the actual air consumption.


1. Motor and converter PTC thermal protection ,in continuous operation on overload and over curre nt protection.

2.Converter has flexibility,and user friendliness.

3.Converter with a large number of maintenance,monitoring and diagnosis function.


4. PLC Control:


1.high definition lcd touch display,intuitive interface,humanized menu structure design.

2.multi- line operation parameters can be reality and history.

3.Uses the original well-well- known electronic control,simple operation,convenient query maintenance.

The benefits of rotorcomp VSD air screw compressor

>Smooth starts and stops within seconds
>Continuous volume flow regulation from 25-100%
>Adjustable-speed drive from 15-60hz
>minimization of wear and maintenance costs
>No power-peaks during start-up
> nearly no idling


Reduce Energy Consumption

The costs of power consumption account for 70% or more of all costs during the operation. The electric charges of running air compressor account for more than 40% of all the electric charges in the factory.

The requirement of compressed air fluctuates violently in different time every day, different weeks, or different months every year. The range of fluctuation is 40% to 80%, Rotorcomp adjustable-speed drive screw compressor can meet the user’s requirement exactly. With frequency conversion soft start reduce in-rush starting current, reduce wear on electrical switch gears and motor windings.

Also maintain less power during starting and stopping of motors and increase protection to motors. Also reduce peak demand and improve power factor.

Pneumatic stability: As the frequency of the screw air compressor using the inverter's stepless speed characteristics, through the controller or the inverter inside the PID regulator, can start gently; on the gas fluctuations in the larger occasions, but also fast Adjust the response.

Start without impact: As the inverter itself contains the soft start function, the starting current maximum rated current within 1.2 times, and the frequency of the general start in the rated current of more than 6 times compared to start the impact of small; Not only the power grid, the impact of the entire mechanical system, but also greatly reduced.
